  1. Why RO Purifiers are considered better than UF Purifiers?

    Why are RO purifiers better than UF?
    What happens to the impurities in the RO purification?
    Are RO Purifiers better than UF purifiers?
    How does RO process work?
    How does a UF purifier work?

    To understand how RO Purifiers score over UF Purifiers we need to delve slightly into the purification process of both these purifiers.

    Lets start with the RO Purifiers first.

    In RO Purifiers purification happens following a process of Reverse Osmosis. To understand the process of Reverse Osmosis, let us take a closer look at the Osmosis process. Osmosis is a process in which water molecules flow across a semi permeable membrane – from a region of lower solute strength to a region of higher solute strength. The solute strength in this case refers to the TDS (Total Dissolved & Suspended Impurities) level of water. The water thus in an Osmosis process moves from across the membrane from a region of lower TDS level to the region of higher TDS level

    In the RO process the Opposite happens. Hence the name Reverse Osmosis. In this process water is forced to move from a region of higher solute concentration to the region of lower solute concentration. This is achieved by pumping water at a higher pressure inside the RO Chamber causing water molecules to be flow through the membrane to the other side leaving behind dissolved solids and other impurities. The impurities that are left behind are drained out through another outlet. The water that passes through the semi permeable membrane in the RO Purifier has a much lesser concentration of TDS than the original inlet water.

    So, when the water has high TDS and is Hard, RO Purification is the most effective

    Since the water needs to be pumped at a high pressure to help it pass across the membrane, RO Purifiers will need electricity to perform this task. Hence the RO Purifiers cannot operate without electricity

    In an UF or Ultra filtration Purifier, a semi permeable membrane like in case of RO Purifier is used but the holes in the UF Purifier are much larger compared to the holes in the RO purifier and as a result water passes through the UF Filter using the force gravity and without any additional applied pressure. Thus UF Filters work without electricity and should be considered for use where the TDS level of water is low and the water is not Hard

  2. Can water purifiers run without electricity?

    Water Purifier without Electricity

    Can water purifiers run without electricity?
    Which types of water purifiers can run without electricity?
    Do non electric purifiers require zero electricity?
    How do online water purifiers work?
    Are the online purifiers portable?

    Some types of Water Filters and Purifiers can run without electricity. These are generally termed asa non-electric water purifiers as they do not need electricity for their operations

    These are typically divided into two types:

    Online and Offline.

    Online purifiers:

    The Online Water Purifiers or Filters are fixed to the mouth of taps.
    These are portable and does not need electricity for use. It uses a resin filter that needs to be changed every month or based upon the amount of usage.

    Offline Purifiers:

    The offline purifiers don’t need electricity for their operation but uses a combination of sediment filters and activated carbon filters. The Storage type water purifiers are very helpful in regioins where there is scarcity of water and where reliable power supply is not available.

    Some of the non-electric water purifiers offered by Zero B are:
